GENERAL DESCRIPTION
•The “wire to wireless” translator module EK-WL8-TRH/AU (further EK-
WL8-TRH or WL8-TRH) is a device which interfaces the hard-wired
Hochiki Enhanced Systems Protocol (ESP) loop to the Ekho wireless sys-
tem.
It expands the analogue system, allowing you to use fire detecting devices
based on the Echo wireless communication protocol for monitoring and
control.
•The translator is powered directly by the analogue loop and is supposed
to be used with control panels that implement the Hochiki ESP protocol for
monitoring and control. In fact, the main function of the device is to act as
an interpreter between the Hochiki and the Ekho protocols.
•The device is supplied with a mounting kit.
•The product complies with the requirements of the AS ISO 7240.17, AS
ISO 7240.18 and AS ISO 7240.25 standards.
NOTE
Ekho refers to a family of addressable, wireless, analogue-intelligent devices
used in the fire detecting field. These devices communicate with the transla-
tor module wirelessly using the “Ekho” protocol. This allows the control panel
to manage and control wireless devices as if they were a part of its loop.

antennas and insert coaxial cables from external 918 MHz antennas (con-
nect the central conductor to socket "A").
NOTE Use external antennas at you own responsibility.

INSTALLATION
Avoid installing the translator close to:
-equipment that uses large amounts of electrical current
-large metal objects, structures or metal ceiling structures
-fluorescent lighting fixtures
-computers, their peripheral and network cabling.
If there are other translators or wireless system expander modules, keep a
distance between them of at least 2 meters. In general, all wireless devices
(child devices included) should be installed at least 2 meters from each oth-
er.
It is recommended to install the translator and expanders at least 2 - 2.5 me-
ters from the floor.
Environmental conditions (temperature, humidity and so on) must be in the
ranges specified at the beginning of this manual.
After having installed the translator, make sure that the translator’s child de-
vices (sensors, call points, etc.) receive a good, strong signal (refer to the
single device’s manuals) in their position of installation.
The translator is mounted on two screws, pre-screwed into the wall accord-
ing to the following marking:
188*
155
180
120
127*
After hanging the translator, it can be fixed on the wall by screwing one or
two additional screws.

WIRING
TRANSLATOR'S WIRING
Before wiring the device, please keep in mind the following:
-refer to and follow national codes of wiring and cabling practice and
other internationally recognized standards;
-loop terminals are polarity sensitive, so connect them according to
the following instructions.
Connect the analogue loop’s cable to the device’s terminal blocks as per wir-
ing scheme in the following picture and per table.
NOTE It's recommended not to install more than 10 WL8-TRH in a single
loop!

FINAL STEPS OF INSTALLATION
Configure the radio system either directly with the translator’s
keyboard/display system or with a personal computer. System configuring
and programming will be described further in this manual.
ATTENTION Due to limitation of short circuit isolators, the panel current
should be limited to 2 Ampere.
PROGRAMMING
ACCESS PERMISSION
Access into "Configuration" menu is possibility after password entering (de-
fault password- "33333"). To change default password is possibility through
"PSW Change" sub-menu which can find in path "Configuration"/"PSW
Change". To do this you should enter the Current password twice and then
New Password.
NOTE In order to restore forgotten password you should do default factory
reset of the system. To do this you should push simultaneously 1 and 3 but-
ton and powered translator. After that on display should appear question
"Clear all?". Answering "Yes" all system will be cleared and will be restore
default password ("33333").

After the ADD command is performed, the translator waits for the installer to
link a child device by pressing the child device's "program button" (see the
specific installation manuals of these devices).
After a device is linked the translator automatically assigns a subsequent
address to it. The whole sequence starts from the address assigned to the
translator ("Start Addr" menu option).
2.The following picture describes the DEL ("delete") command procedure,
which can be applied to devices that are already present in the wireless
configuration:

"!" at the beginning of the line means that there are some problems with the
child device. By using the "State" menu, a user can obtain information about
the general state (alarm/no alarm) and all current faults of the device. Use
the "UP" and "DOWN" buttons to scroll through the faults list.
NOTE After battery replacement in a child device wait at least 5 minutes for
any unexpected fault messages to disappear.
By using the "Control" menu you can switch on and off the LEDs, activate
the "RF link Quality" mode. For detectors, it's also possible to generate an
alarm to test the system.
In the "RF link Quality" mode, child devices indicate the signal strength with
the parent wireless expander by blinking the LED:
-2 blink RED –no connection
-1 blink RED –poor signal strength
-1 blink GREEN –good signal strength
-2 blink GREEN –great signal strength
Devices automatically exit the "RF Link Quality" mode in 15 minutes.

WARRANTY
All translators are covered by a 5-year limited warranty. The warranty is
voided by mechanical or electrical damage caused by incorrect handling or
usage. Translator must be returned via an authorized supplier for repair or
replacement along with full information on the identified problem.
WARNINGS & LIMITATIONS
Devices use high quality electronic components and plastic materials that
are highly resistant to environmental deterioration. However, after 10 years
continuous operation it is advisable to replace them to reduce the risk of re-
duced performance caused by external factors. Ensure the devices are only
used with compatible control panels. Detection systems must be checked,
serviced and maintained on a regular basis to confirm correct operation.
Refer to and follow National Codes of Practice and other internationally rec-
ognized fire engineering standards. Appropriate Risk Assessment should be
carried out initially to determine correct design criteria and updated periodi-
cally.
